CC test question

[Coltay24]

We can’t keep chlorine in our pool, it is currently clear. I’m expecting we will have to slam.
for the CC test does the water have to turn clear and stay clear?

the results I got were the following.

Calcium 125. We have above ground so assuming this might not be important
CYA ~55
TA- 160
FC- 1.5 pm
CC -not sure of test but was past 20 drops and it kept turning back to very slight pink tint. I’m going to retest shortly to be sure.
Ph- 7.4

Once it turns clear, you're done. If you allow it to sit, it will begin to turn pink again.

After you get to clear that is the end point. If u allow it to sit it will become pink again.

I win!

Coltay,
Tell us some more about the pool etc. what have you put into the water lately? Are you not confusing CC and FC testing but the bigger question how are you testing. CYA is considered 60.

 

[Coltay24]

We have only put a bag of Clorox shock in it a week ago. I just started using the tf 100 test kit.
when we had initially opened the pool it was slightly green not to bad, so we added the chemicals the pool store told us to. It cleared the pool up, but would never hold chlorine overnight.
I ordered the kit and started using it to test so I can keep better track myself.
currently our levels are as above. I’ll have to redo the fc and cc. I’m trying to figure out what the best next step to take is.
Should I lower pH to lower TA first or just go straight to Slam. According to pool math I’ll need 13 gallons of bleach based on my levels.

just go straight to Slam

Correct. The pH is fine at 7.4. Use 60 ppm CYA for FC levels. That means a FC level of 24 ppm.
4 gallons of 10% bleach will add 24 ppm FC to your pool volume.

If you can fill in your signature it'll help all involved knowing what you have thereby limiting the back and forth....
Use poolmath to figure out the slam level and make sure you have all the fields filled in for your pool. PH is ok for slamming the way it is and the TA will eventually get lower every time you lower the PH with MA (muratic acid). Be prepared to go through a good amount of chlorine with the CYA you currently have.

ok

 

[Coltay24]

Thanks

ok,

My husband added what we had which was 4 bottles of 7.5% bleach. It brought it up to 15ppm. We are heading to get more, any idea how many you think we should get if we need to keep it up for a couple days?

They were also only 81 ounce bottles, so I need about 3 more I think to bring it to 24.

It is clear but I can tell it is starting to get the slightest green tint to it

 

[mknauss]

Start with 20 gallons.

For chlorine you may enter the pool store as the chlorine will be 12.5%. Being stronger is also using less jugs for the same outcome.

Okay, we will get what we can. Thank you for your help. Should we be testing the OCLT every night?

Thanks, do you know the cost difference from 7.5 to the pool store concentrate?

No. Once the water is crystal clear, then do the OCLT.
